Singapore’s National Environment Agency (NEA) and a team comprising Hyflux and Mitsubishi Heavy Industries (MHI) have signed a waste-to-energy (WTE) PPP project in Tuas.
The project will be developed on a design, build, own, and operate (DBOO) basis. Construction and operation will be carried out by a special purpose company (SPC) in which MHI and Hyflux will own 25% and 75% shares, respectively.
The SPC will consign engineering, procurement and construction (EPC) work to a subsidiary of Hyflux. MHI subsidiaries in Singapore and Japan will supply incineration facility and power generation equipment. Operation and maintenance of the WTE plant will be jointly handled by a JV to be established by MHI and Hyflux.
The plant will have a processing capacity of up to 3,600 tons per day (tpd) and will be capable of generating120 megawatts (MW) of electricity. The WTE plant with stoker furnace type incinerators and generators will go on-stream in the first half of 2019, and be operated, managed and maintained by the Hyflux-MHI Group consortium for a period of 25 years.
The total project cost before commercial operation commences is expected to be approximately S$750 million (US$535.2 million).
To date, the MHI Group has constructed three waste-to-energy facilities in Singapore, including the Tuas South Incineration Plant (TSIP) completed in 2000, which at 4,320 tpd has one of the world’s largest processing capacities.
